This month's Reinventing Parking episode looks at parking lot maps.

Parking lot maps might seem an unlikely viral hit but Parking Reform Network's maps of downtown parking across the USA really did make a splash this northern Spring. They convey a compelling message, with many downtowns having more than 20 percent of their land devoted to parking. That's without even counting podium, underground or street parking.

The maps were created by Thomas Carpenito and a team of PRN volunteers. To discuss the PRN Parking Lot Map project, I spoke with Thomas along with PRN President, Tony Jordan, and PRN Communications Coordinator, Etienne Lefebvre.
